12 supported," on the posts '2. Thet e bars area a'pted to swing rearwardly to t e linting position as shown in dotted lines in ig. 1 "and, m str reupon the upper and forward face of the pl aten 13 diagrammatically shown in Figsljland 3. The eelofeach t e bar Ibars (only'one of which is shown 1) is plvoted'at 1 1;t o an inclined type bar segment 1s connected at 14 to a link 15-pivote at its upper end 16 to a substantially horizontally dlsposed'sub-lever. 17 pivoted at 18 to en ports 19. secured to a plate 20 mounted on t e '17 is pivoted to a depending link 21 connech lever 4. A

posts 3. The forward end of each sub-lever ed at; 22 to the associated ke restoring spring 23 iszconnecte at one end to a sub-lever 17 and at its oppositeend to a fixed pin or finger 24. A depression of a key lever will'move the associated t e bar from the full .to the dotted hne position shown in Fig. 1, the type bars being supported in the 7 normal ositionb a type rest 25.

I Rigi y secure to the inclined tgipe bar segment 12 are upwardly and inwar jectin'g-arms 26 which extend towar each other and terminate forward of the printing point. These fixed arms carryanti-friction 'rollers 27 pivoted to the-arms at; 28 and forming a so-called center guide with which the type bars cooperate in their movements to the printing position. The adjacent contact or guidingsurfaces ofthese anti-friction rollers are spaced apart at a distance which lcorresponds substantially to the width of that portion 29 of-each type bar which is received between the anti-friction rollers, as shown in Fig. 3, in order that the fiat parallel sides of the portion 29 of each type ar 'may be received between and coo e erate with the rollers; to properly 'guide eac type bar in its approachto the rinting POSitlOIl.

Thekpar'allel fixed axes 'o the ant -friction rollers are sodisposed thatwhen a; type bar "contacts with the rollers the movement of the barto or frjgm the pnnting position the receive a turning movement rollers may i around their axes through the contact of the .type bar with the rollers. The-peripheries of the rollers curving toward eal other as shown in Fig.3, receive and properly-deflect the a proaching type bar to the proper posietween the rollers without obstructing the movement of the bar, thus effectively directing the bar so that proper registration with the printing point will be effected. By the employment of the anti-friction rollers 27 wear upon the contact faces of the guide is distributed over greater and con stantly changing surfaces and there is less liability of obstructing the type harin its movement to printing position and alsoiless liability of the type bar sticking and jarn ming in the guide than when fixed, guiding surfaces are employed.

While I have referred herein to the parts 27 as antiirictionrellers and I prefer to einploy rollers of the character shown in the drawing with fixed pivots around whlch the rollers turn, it shouldbe understood that the -term anti-friction rollers is employed in a "type carriers are received and by which they are guided inthe movements thereof to the printing point without arresting the move; ments of the. type carriers, the thiclrnessof' those portions of the type carriers which cooperate with the said rollers corresponding to the distance between those portions of the rollers with which a carrier is in contact when it is in the printing position.

In a typewiitingmachine, the combination of type carriers, and anti-friction rollers which turn on fixed axes and between which the type carriers are received and bygwhich they are guided in their movementsg' to the printing point without arresting the type carriers in their movements to the printing position, the thickness of those portions of the type carriers which cooperate with said rollers corresponding approximately to the distance between those portions of the rollers with which a "carrier is in contact when it is in the printing position.

3. ln-at newritin machine the combination of type carriers each having a guiding portion with flat suhstantiall T parallel sides, and a guide having antiir1ct1on rollers cooperating with the flat substantially parallelv sldes of the guiding portion of'eaoh type bar. 4. In a typewritin'g Inachine,,the' combination of type carrierseach having a guiding portion with flat substantially parallel sides,

and a guide having anth'frictio'n rollers which turn on fixed parallel axes and cooperate with the flat substantiallyparallel sides of the: guiding portionof each type bar.
